Great hotel - not exactly close to Heathrow 5
Taxi to the Hotel would have been $25, we opted for the shuttle bus, didn't have to wait long about 20 mins, ours was the second to last of the day (last shuttle at about 11.30pm), $5 per adult, children free. Journey took about 10 minutes.
Good hotel, a lovely Asian chap on the front desk (didn't get his name, we were very tired) upgraded us to an executive suite, adjoining rooms with free access to the Executive Lounge/Breakfast.
Bliss. Best night's sleep in a month.
